Ho'RsEsHoE HEEL AND TOE CALK SPLITTING. MACHINE.' t

l To LZZ whom, it may concern: I

' cation.

My invention relates to calli-splitting devices which attachy to the anvil and guide a rebounding coldchisel and the objects ofmy vinvention are, first, to provide a machine that can be attached to an anvil by inserting a pin in the hardy-hole; second', to have the cold-chisel adjustable to large or Small'horseshoes, and, third, to have the 4coldchisel raised by a spring, sothat after transmittingl the blow of the hammer it will leave the heated calk, and thereby retain its temper. I attain these objects by the mechanism illustrated in the accompanying drawings, in wl1ich-v v Figure 1 is a plan of my machine. Fig. 2 is a front view, and Fig. 3 is a right side view showing the cold-chisel supported by thej Spring and also showing the heel of a shoe rises a back plate, which terminates` in a split by the action of the chisel.

Similar letters refer t'o similar parts throughout the several views. l t

The base-plate A rests upon the anvil with the downwardly-projecting pin Z inserted into the hardy-hole.v From the base.- plate bracket with flanged sides and through whichA is a hole .to receive the bolt f. From the leftl Side of the base-plate extends an arm bearing upon the anvil and terminating in the socket 7c for holding the hardy. The bracket b has i twoprojections to the front, through which are square holesl which guide the cold.- chisel h, and a slot g, through which'passes the bolt f for regulating the distance between the chisel and relief-block and a hole countersunk on the lower side into which is inserted the bolt cZ for securing the spring c to the said bracket. The reliefblock m is a projection or ledge across the base-plate A to guide the Specication of Letters Patent. Application Afiled November' 6., 1903. Serial No. 180,118.

metal above the same, as shown in Fig. 3. The cold-chisel 71, has the face next to the relief-block m parallel to the line of motion of the chisel and 4beveled on the other side to prevent it binding and sticking in the hot work and'to allow for the spreading of thel and 'One-half coils and then runs straight to the center of one Side of the cold-chisel,where it turns to the left and'passes through the hole in the chisel. To remove the chisel,

loosen the nut e on the bolt d and swing the spring c to the side. l It is clear that chisels or punches can be used in this machine, some preferring to punch a square hole to splitting the calk of a horsej shoe for inserting the steel plugs.

The present method of preparing a shoe for 'inserting the plugs is to have the helper hold the work with the tongs while the master with an ordinary cold-chisel or punch either splits or punches the c'alk, andthe tool remaining in the heated calk very soon de-V stroys the temper, while with my machine the chisel leaving the heated work after each and every blow of the hammer the'temper is not injured and the labor of vone man is saved and the work accomplished with one-half the expense.

What I claim kas my invention, and desire to secure by Letters Patent, is- In a horseshoe heel and toe calk splitting machine in combination with a base-plate,A, hardy-socket, lc, relief-block, m, and cold- Chisel, 7L, the bracket, l), adjustablyarranged to regulate thedistance, from the relief-block,

to the cold-chisel, substantially as set forth. In testimony whereof I have Signed my name to this specification in the presence of two subscribing witnesses.
